Exactly! 

The analogy works only if you don’t try to look as far as the crust.  Interesting to compare this with Hilbert’s Hotel and all the examples of infinite sequences.

I keep hearing the Universe is expanding in comparison to like a balloon inflating, the evidence an apparent red shift observed of matter. We do not observe space red shifting we only observe light/matter interaction red shift, so how from that do you conclude the Universe is expanding when that makes no logical sense or is a any sort of rational thought?
I read this morning that it is now expanding faster than we first thought and soon and the Universe will become cold and the Universe will end, how on Earth doe's any one derive that ?

Its expanding into god of course. And the reason for the anomolies is god.

Seriously though a conventional pressure expantion starts off slow, accelerates eases off and then halts. Like a big crunch when all of the debris falls to the floor.

……expanding into nothing.

If nothing doesn’t exist, how can anything expand into it?  Nit-pickers could have a great time finding a different way to express that idea, though.

It is not expanding into nothing. It may just expand because it is emergent from matter and energy. It is not expanding into but from... Or space could be finite and static and we just shrink  . Or a combination of both processes.
